getting weird side effects???

So its been almost a week that ive been taking 100 mg of mechabol a day. i started the first couple days at 75 and bumped it. Anyways a couple days ago ive started to get an odd cloudy/foggy head feeling every so often through out the day. it just hits me and i can feel it for a second and it goes away. very strange. ive never felt this on any prohormones before. curious if anybody has heard of this and if theres anything i can do to make it stop. btw,in a couple days im stacking it with stano once it comes in the mail. thanks
